To all whom it may concern:

- Be it known that I, WILLIAM N. BEST, a citizen. oi the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of mugs and State of New York, have invented s new and 1 provedCornbustion-Ghember for Gas 01' Oil Stoves, of which the following is afull, clear, and exact description. I

This'invention relates to improvements in combustion chambers for gas,oil, or similar stoves, the object being to provide 0. cheap and durabledevice or so coniplishing important factors in the improvement ofgas-stove operations. First: To provide a means by which the heat willbe increased to assist combustion, and siphonby the agency of the gaspressure through the burner-suificient sir requisite to promotecornbustion in the chamber, and to provide means for the expansion ofthe consuming gases. Second: To effect rhe highest economy in the fuelby controlling and confining the heat in the chamber, not permittinggenerated heat .to go to waste by passing out under the stove. 'lhird:To provide a. combustion chamber of such proportions and form oconstruction than the generated heat will be. dh'ectedage the object tobe heated. 4

Other objects of the invention will e epeer in the general description.

I will describe 2. combustion chamber for gas stoves, embodying riyinvention, then pointout the novel features in the appended claims. I

Reference is to be had to the accompanyin" drawings forming a part ofthis specification, in which similar characters of rcierence indicatecorresponding parts in all the figures.

Figure 3. shows in plan, combustion chamber for 5; go stove, embodyingmy invention; Fig. 2 is a section, on the line 2 2 of Fig. 1' Fig. 3 isit section on the line 33 of Fig. 1; Fig. l is a section on the line 44of Fig. l; and Fig. 5 is o, sectiorifou the line 55 of Fig. 2.

Referring to the drawings, l0 designates the top of an ordinary gasstove having an opening in which the combustion chamber is arranged, andsupported in the stove is on ordinary circular burner 11. The combustionchamber consists of a. metal casing 12, the well of whic is flaredupward and outward, and the burner as clcurly indicated in Fig. 2, maybe located near the lower open end of said casing.

On the periphery of the cnsinget the upper end are outwardly extendedlugs 13 which engage in recesses 14 {owned in the stove top, thuspreventing any rotary displacement of the chamber with relation to thestove top. (he bottom of the chamber is provided with an ribs 16 extendfrom which spaced upward to the top of the chamber.

g Arranged the spaces between the ribs 16 is a packing or lining 170i:refrectory material such, for instance, sscloy, asbestos or the like,this will aid meterially in retaining the heat; within the chamber. Removahly supported on the upper end of the chamber is a spider or grateconsisting of or g 18 having inwardly and downwardly inclinedfingersll}, upon which the vesselto be heated is support-ed. Thering l8is pro- 'ided on its under side with recesses ZOior receiving the lugsl3 and permitting the ring to rest closely upon ihoilpper portion of thechambergthus preventing hea.t irom passing'betwcen scid. parts andcompellin the some to pass upward. against the bottom of ti vessel to beheated, end out bet-ween the outer ends of the fingers, as said fingersare raised somewhat ironi the ring. By inclining the fingers downward,or malt 79 ing the spider convened it will accommodate. vessels inwardlyextended. annular l2 having rounded bottoms. By inclining the wall oh.

the chamber, the products of comhustion h'ill be e1 lowed to expand theypass upward and strike upon all parts of tho-vessel hottom.

Wbile I have shown the device as circular, it is to he understood thatit may he olherviise shaped, without departing from the spirit of myinvention; and further, it may be '2. portion of the stove instead ofremovable as indicated in the drawing.

Having thus described m3 hvention I claimos new, and desire to secure byLetters Patent- 1. A combustlon chamber for liquid or gaseous el bur-1rcrs, consisting 0. a casing having an inwardly-directed flange adjacentits lower end and :1 plurality of inwardly :55 directed spaced ribsextending upward from said flange to the upper portion of the casing,the space between said ribs being widest adjacent the casing-andnarrowing toward 1 the center of the chamber, and refractory material inthe spcccbetween the ribs. 9;)

2. A comhustion'chnmbcr for liquid or gaseous fuel bu ners, consisclngof an inverted, conical, impcrxorate cos rig having :1 wall providedwith a. p11 lty of spaced ribs extending inwardly therefrom, the s'mtwecn ribs being greate adjacent the casing wall the" c the innersurfaces 9;; of said ribs, refractory material within the space betweenthe ribs, and means adjacent the ends or the casing for preventing thelongitudinal displacement of the refractory material.

3. The combination with n liquid or gaseous fuel burner, of animpcrforntc casing surrounding the some, a plurality or blocks ofrefractory m:lLcri:1l cured to the inner surface oi said casing, meansint' 11 with the casing and in cngngemen with one end and the oppositesitlr's of each block for prcvcn'clng the displacement of said blocks,and :1 spider supported uhuvc said burner anrlhavlng downwardly-inclinedradial fingers.

4. A combustion chamber for liquld or gaseous fuel burners, comprising acasing having its wall inclined upward 10 upward and outward,

and outward and having an annular flange at theinnei" and lower end ofthe casing, spaced ribs exi'enaiing inwardly from said casing, andrefractory blocks in the spaces between the ribs, the of the blocksfacing toward the interior of the chamber presenting a smoothuninterrupted suiliuue.

5. The combination with a gas 0! oil sto've having an opening andrecesses formed in the top, of :1 combustion chamber consisting of acasing having iis Avail inciined lugs .01; the upward end of said sidesof the ribs and the sidescasing, a ring lugs. N
